Why OT security matters
OT environments control the physical processes that power industries such as manufacturing, energy, transport, and water management. Unlike IT systems, OT prioritises availability, integrity, and safety, and has unique challenges relating to asset lifecycles and obsolescence, governance, OEM dependencies, and specialised protocols — making traditional approaches to cyber security insufficient.
Today, 72% of OT breaches start in the IT environment before moving into operational systems. Legacy assets, insecure remote access, and poor segmentation leave critical processes exposed to increasingly sophisticated cyber threats.
Without the right protection, the impact can be severe: from operational shutdowns to reputational damage, financial loss, and even risks to public safety.
Integrity360’s OT Security Services portfolio gives you the confidence to operate securely and resiliently, no matter the threat.

Managed OT Security Services
Ongoing specialist support to operate your OT security capabilities delivering compliance-ready reporting, risk-based assurance and control mapping aligned to NIS2, CRA, DORA, UK CAF, ISO 27001, IEC 62443 and NIST frameworks.
Managed OT Security Posture
OT security starts with visibility. This service delivers passive discovery, asset inventory reporting, Purdue mapping, vulnerability context, attack-path insight, critical asset grouping, remediation tracking and monthly risk reviews. Includes platform management and customised dashboards and reporting to ensure risk is known, managed, and reduced, eliminating critical exposures to threats in your environment.
Managed OT Access Security
Who has access to what in OT is crucial. This service provides secure remote access, vendor onboarding, third-party access, MFA, approval workflows, session recording, access reviews, PAM integration and emergency access governance. Includes platform setup, configuration and ongoing management.
Managed OT Threat Detection
With increasing targeting of OT environments, security monitoring is essential. With this service we detect and investigate OT threats with 24x7 monitoring, escalation and response support with three service tiers.
Managed OT Network Security
Network security and proper segmentation is crucial both within OT and between OT and IT environments. This service ensures and manages best practice firewall policy, segmentation governance, rule reviews, change control, DMZ monitoring and zero-trust architecture support, aligned with IEC 62443 principles. Includes firewall platform management, health monitoring, and infrastructure incident response in the event of failures.
Managed OT Resilience and Recovery
In OT, the end goal is safety, operational continuity and resilience. This service enables this through a combination of complimentary features that include assurance of response playbooks, tabletop exercises, ransomware simulations, recovery readiness assessments, specialist investigations, and major incident response.
Managed OT Threat Detection tiers
-
OT Threat Monitoring: This service provides platform management and 24x7 threat monitoring underpinned by specialist OT network threat detection solutions.
-
OT SOC + SIEM: This service also includes a SIEM and correlates OT alerts with identity, firewall, remote access, endpoint and IT telemetry, widening the lens for detectable threat actor activity in and around the environment
-
Hybrid IT/OT MDR: Integrate OT detections with enterprise SOC telemetry for coverage across IT and OT. For customers who need an end-to-end provider of 24x7 threat monitoring across the full combination of their IT and OT estates.

Operational Technology FAQs
What is operational technology (OT) security?
OT security involves protecting industrial systems such as SCADA, PLCs, and ICS environments from cyber threats. These systems control physical processes in sectors like manufacturing, utilities, energy, and transportation.
Why is OT security different from IT security?
OT systems were traditionally isolated and designed for safety and availability, not cyber resilience. They often run legacy technologies, have limited patching options, and require specialised approaches to avoid operational disruption.
What challenges do organisations face with OT security?
Key challenges include:
-
Legacy systems with poor security controls
-
Limited visibility into OT assets
-
Converged IT/OT environments
-
Supply chain risks
-
Inability to apply traditional security tools
-
Meeting compliance with NIS2, ISA/IEC 62443, and DORA
What services does Integrity360 provide for OT security?

-
OT risk assessments and gap analysis
-
Network segmentation and architecture review
-
